The Type of Milk That May Increase the Risk of Heart Disease
Understanding the health implications of full-fat and low-fat milk based on decades-long research findings.
The Milk in Question Is Full-Fat Milk
The Study Followed People for Decades
More Than 73,000 People Were Included
The Concern Is Cardiovascular Mortality
Saturated Fat Is Part of the Explanation
Low-Fat Milk Looked Safer in This Study
The Evidence on Dairy Is Still Debated
Cheese, Yoghurt, and Milk May Not Act the Same Way
The Best Choice Depends on the Whole Diet
The Practical Message Is Moderation and Awareness

Milk has long been treated as a simple symbol of health: calcium, protein, strong bones, and an easy daily habit. But recent research has made the conversation more complicated, especially when it comes to the difference between full-fat milk and low-fat milk. A large Norwegian study followed 73,860 people over roughly three decades and found that whole milk consumption was associated with higher cardiovascular and all-cause mortality, while low-fat milk was not linked to the same increase.
That does not mean one glass of full-fat milk is dangerous, or that every person must avoid it completely. Nutrition is rarely that simple. But the findings do suggest that the type of milk people drink may matter over the long term, especially for those already watching cholesterol, saturated fat, weight, or heart disease risk. Here are ten key points that explain what the study found and why it matters.
